Ti-6Al-4V alloy is the most commonly used metallic material in the manufacture of orthopedic implants. The main inorganic phase of human bone is calcium hydroxyapatite (Ca-10(PO4)(6)-(OH)(2), HA). To achieve better biocompatibility with bone, metal implants made of Ti-6Al-4V are often coated with bioceramics. Dip-coating techniques scarcely are used to apply HA onto metallic implants. New dipping-solution recipes to be used for HA coatings are described in this work. Scanning electron microscopy and X-ray diffractometry have been used for sample characterization.

EMULSION-BASED PROCESSING AND CHARACTERIZATION OF BIOMIMETIC HYDROXYAPATITE MICROSPHERES BY USING CALCIUM PHOSPHATE CEMENTS Öndin, Nilsu; Durucan, Caner; Department of Metallurgical and Materials Engineering (2022-11-22) Synthetic materials for bone defects have been widely used for biomedical applications. One of these materials is bioactive ceramic-based microspheres in the size range of couple 100s m. These microspheres are used for irregular defect filling operations due to high packing efficiency. The spherical shape also increases the surface area, reactivity, and cell adhesion. The osteoconduction (bone tissue growth) is the primary concern for hard-tissue replacements and grafts. Alpha-tricalcium phosphate (-TCP, ...
Co-doped hydroxyapatites as potential materials for biomedical applications YILMAZ, BENGİ; ALSHEMARY, AMMAR ZEIDAN GHAILAN; Evis, Zafer (2019-01-01) Hydroxyapatite (HA) is a synthetic biomaterial resembling the composition of mammalian hard tissue and thus, it is widely employed as a bone graft material, hard tissue engineering scaffold and coating layer for metallic substrates. Biological apatite is non-stoichiometric in nature. It is composed of small crystals and characterized by poor crystallinity and relatively high solubility with respect to stoichiometric HA. Chemical compositions of these crystals consist of Ca, P and trace amounts of various io...
Biodegradable hydroxyapatite - Polymer composites Durucan, Caner (2001-04-01) The fracture of bone due to trauma or due to natural aging is one of the most frequent types of tissue failures. Treatment frequently requires the implantation of ct temporary or permanent prosthesis. The implanted materials may include the components of artificial joints, plates, and screws for fracture fixation. Typically, such implants are intended only to provide structural support or to serve as templates for bone re-growth. In general they are intended to remain in place for the life of the patient or...
Tissue engineered cartilage on collagen and PHBV matrices Kose, GT; Korkusuz, F; Ozkul, A; Soysal, Y; Ozdemir, T; Yildiz, C; Hasırcı, Vasıf Nejat (2005-09-01) Cartilage engineering is a very novel approach to tissue repair through use of implants. Matrices of collagen containing calcium phosphate (CaP-Gelfix (R)), and matrices of poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid) (PHBV) were produced to create a cartilage via tissue engineering. The matrices were characterized by scanning electron microscopy (SEM) and electron diffraction spectroscopy (EDS). Porosity and void volume analysis were carried out to characterize the matrices. Chondrocytes were isola...
Biomechanical Evaluation of an Injectable Alginate / Dicalcium Phosphate Cement Composites for Bone Tissue Engineering Alshemary, Ammar Z.; Bilgin, Saliha; Işık, Gülhan; Motameni, Ali; Tezcaner, Ayşen; Evis, Zafer (2021-06-01) Biocompatible dicalcium phosphate (DCP) cements are widely used as bone repair materials. In this study, we aimed to investigate the impact of different amounts of sodium alginate (SA) on the microstructural, mechanical, and biological properties of DCP cements. Beta-tricalcium phosphate (β-TCP) was prepared using a microwave-assisted wet precipitation system. Lattice parameters of the obtained particles determined from X-ray diffraction (XRD), were in good match with a standard phase of β-TCP. Scanning ele...
